5 Claims.

This invention relates to bags and more particularly to an improved method of. attaching to bags a closure member oi.' the flexible interlocking type, commonly known as the slide-fastener.

The slide-fastener type of closure has been applied to various types of articles in the nature of clothing and luggage. `Slide-fasteners, which may bel purchased in any Adesired lengths for applica- -tion to articles oi manufacture, consist of two strips of tape, each having fastened to one of its edges a row of small metallic members, which rows are guided into interlocking engagement with each other by a guide member slidable along said rows. The said tape is oi textile material and it is by sewing this tape to the article that the slide-fastener is secured in place.

Such articles as ladies handbags, tobacco Vpouches, and other small bag-like containers are often made up of an outer material and alining material, and it is necessary to fasten both of these materials to the tape of the slide-fastener. In making this fastening, one or more bulky and unsightly seams have been used and as these seams occur adjacent the open end oi the bag, they are very noticeable and obviously very undesirable.

It is, therefore, the object o! the present invention to provide an improved type of bag having a slide-fastener closure, and to provide a method of forming the bag and attaching to it the slidefastener closure member that will result in a nished product oi neat appearance and simple, durable construction.

As a result of my improved method of forming a bag, all of the exposed seams are at seams rather than folded seams. The term flat seam, as used herein, denotes a seam that is formed by laying two pieces of material face to face, stitching them together on aline parallel to their edges, and then spreading them apart so that the flnished seam is flat in appearance.

I have chosen to illustrate and describe my invention as applied to a ladys handbag, but it should be understood that the invention is in no way limitedby this disclosure as it is equally well adapted to various other types of' articles.

A preferred form oi my invention is'illustrated in the accompanying drawing and described in greater detail in the following specification, in which further of its objects and advantages are e apparent.y

the bag illustrated inv Fig. l will be referred to as Ihaving a top-edge generally indicated at- 10, to which is secured a slide-fastener 11 by means of which the top edge may be opened or closed. What will be referred to as the bottom edge of the bag is generally indicated at 12, and the ends of the bag are designated by the numeral 13.

A slide-fastener of conventional design is illustrated vinlig. 2 as comprising two pieces of tape 14having theirvinner edges rolled or beaded as at 'l5 to support rows of metal members 16 which may be drawn into or out of interlocking relationship with each other by means of a slidable'guide member 17.

Following is a description of the'method I employ in making a bag and in securing the material forming the bag shown in Fig. l to the slide-fastener closure member illustrated in Fig. 2:

In general, bagsv of this type comprise an outer material suitable for the particular utility or ornamentation desired, and an inner or lining material. In many cases it is desirable, in order to give body or durability to the bag Walls, that one or more layers of interlining material be used. In the present instance I have illustrated a bag which is composed of an outer material 18, a single interliner 19, and a lining material 20.

The rst step in forming the bag is illustrated in Fig. 3, in which figure the outer material 18 and the interliner 19, which form the walls of the bag, are shown as continuous pieces so that the bottom 12 of the bag is seamless. The outer material 18 and the interliner 19 are placed against each-other and folded in a position that is the reverse of the position that they will eventually occupy; or, in other words, are arranged inside out. The slide-fastener closure is then placed in a reversed-position with the rows oi metallic members 16 extending inwardly and the top edges 10 of the outer material and interliner are stitched to the tapes i4, the stitching being illustrated at 2l. The position of the bag in this form is then reversed, or it is turned right side out, as illustrated in Fig. 4, and pieces `for lining material 20, which are rectangular and or substantially the size of the walls of the finished Leraars jacent the edges of the materials through which l.

After the seam 24 is made, the lining is inserted into the bag so that the parts assume the positionsshown in cross-section in Fig. 6.

In a bag made according to the method described above, all of the seams adjacent the slidefastener closnre, as well as all of the seams that are ordinarily visible, partioularly'from the outside of the bag, areV of Vthe flat type so that the general apearance of the bag is greatly enhanced. In other words, the stitching is all invisible as it isy done from the wrong side of the materials which are then reversed to form the iinished bag. In the ordinary bag, where the stitching is made from the right side of the materials and from the outside of the bag, it is necessary to fold the materials adjacent their stitched edges. The result is a bulky seam and exposed stitching in contrast to the ,flat seam and invisible stitching ber, and-due to the use of flat seams for securing edges o1 thosooms formed by solo Smohlng boing the bag portions to the closure member these concealed between the outer material and the linseams can be'made closerv to the row of metallic lng malorlolelements of the slide-fastener than is otherwise 5 A bog of the character described comprising practical, thus leaving less of the tape portions 14 an outer mo'oolal" o llnlng material and a Sllde' exposedi v This is an advantage because the tape fastener closure member including tapemembers members 14 are usually formedv of some very for atlaollmont to the materials of the bag stltoh.' durable material, the ilnish of which is not in lng connecting solo topo members to sold outer keeping with the .materials used for the Youter and'llnlng materials' Sad Outer material form' portion and lining. of the bag.

Y ANNETTE S. LUNN.

Having described my invention, what I claim and desire to secure by Letters Patent iswith-the slide-fastener in a reversed position between lts edges, reversing the outer material and the slide-fastener and sewing the lining material to the slide-fastener, again reversing the outer material and sewing the end edges of both the outer and lining materials, and then reversing both the fouter and lining materials, whereby all the raw edges of the seams formed by said sewing operations will be concealed between the outer material and the lining. y
